Water soil improvement
On water and offshore foundation treatment, the foundation treatment and reinforcement of offshore construction projects such as reclamation ports, offshore airports, artificial islands, etc., are much more difficult than on land construction due to the multiple effects of uncertain factors such as seawater tides, wind waves, and ocean weather. In order to effectively solve the problems of offshore soft soil foundation treatment and maintenance, compared to traditional methods, new technologies such as PVD plastic drainage boards on water and deep cement mixing piles on water are adopted, The construction cost is lower and the impact on the marine environment is less, making it one of the effective methods for soft foundation treatment at sea.
Construction Technique
Water PVD technology
Water PVD technology
The water PVD (plastic drainage board) engineering ship has two PVD (plastic drainage board) engineering ships, which use a shallow draft flat boat and a gantry type amphibious insertion machine for insertion. It adopts advanced GPS positioning and can meet the requirements of engineering design for insertion depth and spacing. The hard soil layer has strong penetration force and construction efficiency. The cumulative construction of water PVD (plastic drainage board) has reached 35 million meters, which can meet the requirements of offshore construction and strong anti surge It has stability, safety, and sustainability.
